How to measure potentiometer resistance

Web15 jul. 2024 · Hello @socokid - If you are able to remove the potentiometer from your circuit, you can use a multimeter to measure the total resistance of the pot. Set the multimeter to ohms and place the red lead on the red wire and the black lead to the brown wire. If your meter is not autoranging, you may need to try multiple resistance ranges to … Web6 apr. 2024 · Below is the derivation to explain the working principle of Potentiometer: According to Ohm's law, V = IR. Where I is current, R is total resistance, and V is voltage. Now, R = ρL/A and V = I (pL/A). Where ρ is resistivity and A is the cross-sectional area. With ⍴ and A constant, I is also constant for a rheostat. Hence,
